Appiieation inea January 14, 1920. seriai No. 351,2;20.

To all whomtmay concern.' Be it known that LJoian FRANois OMnn- LEY, a subject of the King of Great Britain, and a Vresident of Mount'Vernon, in the county of Westchester and State of New York, have invented a new and YImproved. Machine-Gun, of which the following is a fullclear, and exact description.

The invention relates to machine guns such as shown and described in the Letters Patent of the United States, No. 1,307,316, grantedto me on June 7, 1919, and in the a plication for Letters Patent of the United tates, Serial No. 266,194, filed by meqon December 11, 1918. v

provide a new and improved machine gun of the type above referred to and arranged to'supply the cartridges to the barrel in use at the time froman intermittently revolving magazine wheel instead of from .a cartridge belt. u I v Another objectis to permit of quickly and conveniently replacing anempty magazine wheel by a filled one.

With these and other objects in view, the invention` consists ,of` certain novel features Vof construction as hereinafter shown and Ydescribed and then specifically pointed out in the claims. l f l A practical embodiment of the invention is represented in the accompanying drawings forming apart of this speciiicatiom'in whichy similar characters of reference indi cate corresponding parts vin all the views.V

Fig. and f Fig.r8'is a sectional perspective view of a portion of the magazine cartridge wheel.

The gun body or main frame 10 of the machine gun is preferably made in two parts 71s a plan view of the cover ring;

. 11 and 12 fastened together by transverse screwsl3, and tliegsaid parts 11 and 12 are provided with transversely extending interlocking tongues yand grooves, one fitting into the other, to securely hold the parts against longitudinal'movement one on theother, as willbe readily understood by reference to Fig-2. The forward'end of the part v12 of lthe gun bodylO 'is provided withl a: pivot 14 on which aremounted reversible barrels 15 and 16 of the type more fully shown and described in the Letters Patent and the application above referred to, so that further description of the same is not deemed necessary, litv being sufficient. tovv state-that the barrel 1n uppermost position at the time is the one through4 which the bullets are red. Each ofk the vbarrels 15 andf16 is provided withea bore 17,)of .which the bore of the f uppermost barrelis successively in register with cartridge seats 20 formed infa cartridge magazine wheelj21secured on the upper end of a shaft 22 journaled in suitable bearings ,arranged on the part 12 of the gun body shaft 27 journaled in tliegun body 10, as

plainly indicated inFig. 3. The rear end of the shaft 27fpasses out of the'gun body 10 and along the under side thereof, and on this rear end lis secured a bevel gear wheel 30 in-mesli with a bevel gearwheel 31 secured on a transverselyextending shaft 32 journaled in suitablebearings 33 attached to the under side of the gunbody 10, as plainly shown in Figs. 1 and 3. .A crank arm 34 is attached to the right-hand side of the shaft 32 to permit the user of the gun to conveniently` turny the shaft 32 with a view to rotate the shaft 27 Ywhich by the vgear wheels 26, 25 rotates the shaft 22 and 'consequently the magazine cartridge wheel I 21 to move the cartridge seats 20 successively tridge 40 with the bullet V41 extending out- Iwardly within close proximity tothe pe ripheralface of the magazine wheel 21, as plainly indicated in Fig. 3. Each of the seats 20 of the magazine wheel 21 is formed partly on the top of van annular ange 42 Aprojecting from the hub 43 of the `wheel and` vpartly in the under side of a detachable covering ring 44 removably fastened by suitablespring vcatches 45 tothe hub43, as

plainly indicated in Fig. 4. The hub of the magazine Wheel 21 is provided at the under side with a recess 46 and the side Wall 47 of this recess 46 is provided with vertical slots 48 each of a Width corresponding approximately to the diameter of a cartridge adjacentthe cartridge rim 49 so that the latter abuts against the inner face of the Wall 47. The top of each slot 48 is at the top of the hub 43 and the inner'portion of the slot at the top is enlarged sidewise for the passage of the rim 49 of the cartridge. Bythe arrangement described the magazine wheel is loaded with the cartridges by droppingl the same with the rim ends down the slots 48. The covering ring 44 is provided along its inner Wall With vertical ribs 50 which fit into the slots 48 and rest at their bottoms on top of the cartridges 2O in front of the rims 49 to securely hold the cartridges in place during firing. The hub 43 is removably held on the upper end of the shaft 22 by a nut 55 screwing on the threaded reduced top portion 56 of the said shaft 22 to permit of conveniently removing an empty cartridge Wheel from the shaft 22 and replacing it by a filled one. Itis understood that when a cartridge Wheel is removed, the covering ring 44 can be readily removed from the hub 43 on retracting the catches 45 and lifting'the ring ofl' the flange 42.

The empty shells of the cartridgesv 40 can now be dumpedV out. The seat portions of the flange 42 can now be readily filled With cartridges'40, after which the covering ring 44 is replaced and locked in position by the catches 45. By reference to Figs. 1 and 3 it will be noticed that the gun body 10 is provided at the top with a cut-out-portion 58 to make the top of the horizontally disposed cartridge magazine wheel 21 flush with the top of the gun body 10 with a view to permit proper sighting of the gun.

In order to fire the cartridges 40 as they successively move into operative position relative to the bore 17 use is made of a firing pin 60 mounted on a slide 61 mounted to reciprocate longitudinally in a suitable bearing 62 formed in the gun body 10,v as plainly shown in Fig. 4. The slide 61 is provided with a slot 63 through which extends they 'shaft 22, and the said slide 61 is pressed in a forward direction by a spring 64 coiled on a rod 65 mounted to slide in a bore 66 formedin the gun body l0 (see Fig. 3). The top of the slide 61 is provided with a V-shaped tooth en aging a toothed' Wheel 71 secured tothe sha t 22 so that when the latter is rotated a longitudinal reciprocating motion is given to the slide 61 to cause the Vring pin 60 to strike the rim 49 of thecartridge 40 in register at the time with the bore 17 of the gun barrel 15 or 16 in uppermost position at the time. VIt is understood that motion to the left is imparted to the slide 61 by the teeth of the toothed wheel 71 acti-ng on the tooth 70, and return or firing movement is given to the slide 61 by the action of the spring 64. y

In using thegun, the operator turns the crank arm 34 thus causing the magazine Wheel 21 to rotate continually. Atthe same time the firing pin 60 is actuated to lire the cartridges 40 successively and at the time they are in register with the bore 17.

The forward end of the gun body 10 is mounted on a suitable support 80, preferably of the construction shown and Adescribed in the application for Letters Patent above referred to, so that further description of the same is not deemed necessary.

The gun body 10 and the barrels 15 and 16 are provided with suitable rear andKV front sights 90 and 91, of any approved construe'- tion. Y

Having thus described my invention, I

claim as new and desire to secure by LettersA Patent 1. In a machine gun, a gun body provided with a barrel, a horizontally disposed 'carregister successively with the said barrel, each seat being adaptedto hold a single cartridge with the bullet thereof at the outer end, a vertically disposed shaft journaledin the said gun body and on whichV the said magazine wheel is secured to rotate Vwith the shaft, means for driving the said shaft, a spiingpressed firing pin mounted toslide in the said gun body and adapted to fire' the cartridge in register at the time with the said barrel, and means connected `with the to the said firing pin.

3. In a machine gun, a revolubleccartridge magazine Wheel providedV with a body having a hub and an annular Yflange projecting integrallyA vfrom the rim of the hub theY latter having a central recess, a ring removably fitting on the said hub andV overlying the'ksaid flange, cartridge seats formed partly in the said flange and partly' in the'said ring and opening at .their inner ends into the said central recess, the cartridge seats being disposed radially, the inner top portion of each cartridge seat being yenlarged sidewise for the passage of the rim of a cartridge, the enlarged seat portion opening into the said recess, and locking means locking the said ring in place on the hub. e
